In Australia, assault is the leading preventable cause of death, (traumatic) brain injury (TBI), and mental health problems, particularly amongst women/vulnerable populations.

The COVID-19 pandemic has exacerbated the incidence rate of assault. Our vision for the next five years is to develop a novel integrative neuroscience research program to characterise, predict and treat mental health deficits in assault victims that have sustained TBI. It is expected that this information will guide the development of novel personalised treatment plans and prediction models and by doing so it will inform policy and practice to enhance the mental health outcomes of people living with TBI.

Study focus

Track the course of their mental health trajectories and pathophysiological mechanisms in assault victims with traumatic brain injury.

Sampling frame

Assault patients will undergo assessments at 5 time points during the acute, subacute (2 weeks, 1, 3 months), and chronic periods.

Data access

The data is not publicly available.

Time period

2021 - 2025

Original sample size

250

Intergenerational

No

Imaging

Brain MRI data will be acquired in the Metropolitan Melbourne participants, to examine the temporal and spatial profile of neuropathological mechanisms related to mental health. Imaging will be performed on a dedicated research 3-Tesla Siemens Prisma MRI scanner located at The Florey Institute in Melbourne.

Linkage

We will extract clinical characteristics of the participants from the participant’s medical file (after informed consent) using the medical records of the hospitals.

Biosamples

In future study

Ethics approvals or requirements

Yes, high-risk ethics application (ethics committee St Vincent’s Hospital)

Waves

Wave Year / Period Age (mean, range) Eligible sample
1 Acute – shortly after injury TBC 250
2 Subacute – 2 weeks after injury TBC TBC
3 Subacute – 1 month after injury TBC TBC
4 Subacute – 3 months after injury TBC TBC
5 Chronic – 12 months after injury TBC TBC
6 Chronic – 18 months after injury TBC TBC
